Abstract
The utility model provides an ignition plug type cylinder pressure meter which has an integral structure. The ignition plug type cylinder pressure meter comprises a meter body, a pressure meter and a stainless steel header pipe. An air passage is disposed in the meter body, a check valve is disposed on the air passage, the upper end of the air passage is communicated with the stainless steel header pipe which is communicated with a three-way branch pipe; the pressure meter is disposed at one exit end of the three-way branch pipe; the lower portion of the meter body is provided with an ignition plug probe; the outer surface of the ignition plug probe is provided with a connecting thread; and an inner hole of the ignition plug probe is communicated with the air passageway. The ignition plug probe is designed according to the actual structural size of an engine ignition plug, so that the volume of an engine combustion chamber can be simulated actually and measurement errors can be reduced. A high-accuracy pressure transmitter is employed, so that the measured cylinder pressure is more accurate, repeatability and practical application value are improved, and reading errors are effectively prevented. The ignition plug type cylinder pressure meter is integral in design and compact in structure, occupies less space, is convenient for installation and arrangement, and is easy to control and maintain.
Description
Technical field
The utility model relates to a kind of automobile detection part, especially for the spark plug type cylinder that the engine bench test cylinder is pressed, presses table, belongs to automobile technical field.
Background technology
At present, the cylinder that is applied to engine bench test presses list structure to generally include tensimeter, air release, retaining valve, rubber hose, the first-class composition of monofilament.Its principle of work is: the monofilament head of cylinder pressure table is screwed into engine cylinder cap spark-plug hole place, by dynamometer machine towing astern or motor dragging engine rotation, piston operation produces compression pressure, compression pressure backs down the retaining valve in the tensimeter pipeline, the engine cylinder pressure value that the data that show by tensimeter record, let out tensimeter by air release after measuring.The problem that existing cylinder presses list structure to exist is: the monofilament head is only as the web member with engine cylinder cap, it and spark plug are deposited larger difference dimensionally, and structure is inconsistent, therefore more or less can occupy former machine engine combustion chamber volume, cause measured cylinder pressure of engines value out of true, can not be for each cylinder compression pressure of engine effectively accurately be provided at R﹠D motives; In addition, existing cylinder pressure table can only carry out reading by tensimeter, has reading error, detects Data duplication poor.
The utility model content
The purpose of this utility model is the drawback for prior art, but the former machine engine combustion chamber volume of a kind of real simulation and the accurate spark plug type cylinder of reading pressure table are provided.
Problem described in the utility model realizes with following technical proposals:
A kind of spark plug type cylinder is pressed table, special feature is, it is structure as a whole, and its formation comprises table body, tensimeter, stainless steel house steward, be provided with air flue in described table body, air flue is provided with retaining valve, and the air flue upper end is communicated with the stainless steel house steward, and the stainless steel house steward is communicated with tee branch, tensimeter is arranged on an endpiece of tee branch, described table body bottom is provided with the spark plug probe, and the outside surface of spark plug probe is provided with connecting thread, and the endoporus of spark plug probe is communicated with air flue.
Above-mentioned integral type spark plug type cylinder is pressed table, and the total pipe port of described stainless steel is provided with pressure unit, and pressure unit is threaded with the stainless steel house steward.
Above-mentioned integral type spark plug type cylinder is pressed table, and the external diameter of described spark plug probe is 12 millimeters, and high 17 millimeters, the pitch of connecting thread is 1.25 millimeters.
Above-mentioned integral type spark plug type cylinder is pressed table, and described tensimeter is threaded with tee branch, at this connection of thread, is provided with the thread locking glue-line.
Above-mentioned integral type spark plug type cylinder is pressed table, and another endpiece of described tee branch is provided with air release.
The utility model is pressed the measured cylinder pressure of engines value out of true of list structure for available engine engine bench test cylinder, and the not good enough problem of reading repeatability is improved, and substitutes web member monofilament head with the spark plug probe, and be provided with pressure unit on pipeline.Due to the requirement design according to engine spark plug practical structures size of spark plug probe, simulated engine combustion chamber volume really, Reduce measurement error; Adopt the high-precision pressure transmitter, measured cylinder is pressed more accurate, improve repeatability and actual application value, effectively avoid reading error.The utility model integrated design, compact conformation, take up room little, facilitates mounting arrangements, is easy to control and maintenance.
